Suspended MP Geoff Shaw has issued a long-awaited apology to the Victorian parliament and the people of the state on Friday night, albeit in the trappings of a comedy show.

Victoria's parliament has been the scene of high farce since Shaw resigned from the Liberal party in March 2013 and nabbed the balance of power in the state. But on Friday night, in a show at Melbourne's Wheeler Centre, the comedy was intentional.

Shaw, who was this week suspended for misusing his parliamentary vehicle and fuel card conceded, at the pressing of Sammy J, that he was 7% guilty of rorting.

"Sometimes you go up to the boundaries, and sometimes people don't like it," Shaw said of privileges committee findings that he had used his parliamentary car in aid of his hardware business. "There was an investigation, they found nothing wilful."

This week he was suspended from parliament and fined, and asked to issue an apology. He obliged: "To the people of Victoria, I'm exceptionally sorry, and I apologise to parliament and to the good people of Victoria."

The famously defiant MP said he regretted the ABC radio interview in which he threatened to bring down the parliament, triggering the drama that lead to his suspension. But he wouldn't have really brought down Denis Napthine, he insisted. "The message to the premier was lift your game," he said.

Shaw said he would run for Frankston again in November's state election, regardless of the outcome: "If I win I win, if I lose I win. There's life after politics, life goes on."

Shaw confessed that his week had been the worst in recent memory, but only in parliament. "Today I walked through Frankston, and it was fantastic. I couldn't get out of Coles for about 45 minutes, it was terrific," he said.

Asked to say some "nice things" about the former speaker, Ken Smith, Shaw demurred: "Nice things? Okay. Next question."

Smith, a bitter enemy of the Frankston MP, spared him expulsion this week after backing down on an earlier threat to vote with Labor to have Shaw banished permanently from the chamber.

As always, he attracted controversy. Recalling an incident in which he was alleged to have called the opposition leader, Daniel Andrews, a wanker, Shaw insisted he had only said "whacker", blaming the misunderstanding on "these Labor women on the other side [who] can't hear at the best of times".

"Shame!" came the cries from the audience. The refrain was heard again when the MP's evangelical crusade against abortion was raised.

"I'm pro life, and it believe that every child that had a heart beat shouldn't be killed," Shaw said, adding that Victoria's 2008 bill to decriminalise abortion was a "horrendous law".

Sammy J touched on other Shaw controversies, asking the MP about his 2010 maiden speech in which he referred to "God, the creator" as the traditional owner of the land on which parliament stood.

At the time, it was taken as a slight against Indigenous Australians. Not so, said Shaw. "I think the way that people accept what's being said is up to them, but that meaning wasn't meant there at all," he said.

Sammy J closed the night by sketching a future in which a statue of Shaw might be erected in Frankston, with a plaque bearing his final words. He asked the MP what it might say.

"Sorry, Victoria!" an audience member shouted.

"The guy who did the best for Frankston," Shaw suggested, before retrieving his bagpipes from backstage. He played Amazing Grace.
